Hello,

probably i may not frame the questions in right way, as my knowledge is limited on electrical motors. but still i do my best...

what are the different type of motors? Part Winding Motor/Star-Delta Motor/any other??

Why different motors are used (PW/Star Delta)?

Which one is widely used in supermarket refrigeration in europe?

what is the difference between part winding and star delta motors?

i am bit confused, whether connections in terminal box makes the difference in different motors (PW/Star Delta) or is it motor winding?

Thanks
